Image of the Week: Simulations Reveal Unusual Death for Stars

Massive primordial stars, between 55,000 and 56,000 times the mass of our Sun, may have died unusually. In death, these objects — among the universe’s first generation of stars — would have exploded as supernovae and burned completely, leaving no remnant black hole behind.

Astrophysicists at the UC Santa Cruz and the Univ. of Minnesota came to this conclusion after running a number of supercomputer simulations at the Department of Energy’s (DOE) National Energy Research Scientific Computing Center (NERSC) and Minnesota Supercomputing Institute. They relied extensively on CASTRO, a compressible astrophysics code developed at the DOE’s Lawrence Berkeley National Laboratory’s (Berkeley Lab’s) Computational Research Division (CRD). Their findings were recently published in the Astrophysical Journal (ApJ).

VICE’s coverage of the protest


Masses of pro-democracy protesters continue to pack the streets in Hong Kong, defying police who have responded with tear gas. The demonstrators are angry that Beijing has insisted on vetting all candidates for the territory’s next chief executive.

Here’s a closer look at the issue and what’s at stake.

The maps of Piri Reis, a 16th-century Ottoman Admiral famous for his maps and charts collected in his Kitab-ı Bahriye (Book of Navigation), a book which contains detailed information on navigation as well as extremely accurate charts describing the important ports and cities of the Mediterranean Sea. In 1513 he produced his first world map, based on some 20 older maps and charts which he had collected, including charts personally designed by Christopher Columbus which his uncle Kemal Reis obtained in 1501 after capturing seven Spanish ships off the coast of Valencia in Spain with several of Columbus’ crewmen on board.
